Important!:
The water animal graphics are mine, the land animals are by Lobby.
Before using the animals, it is best to place a road around the area where you want them to stay.
The fish do not die out by themselves. The animals will, if the enclosed area is greater than 3 tiles wide by 3 high and up to 70x70, 50x100, etc. They spread when yellow, spread more when red, turn green when dead. The land animals remove themselves when the last yellow one ceases to exist. If there are no road limiters, you will have to pause the game and remove them yourself once they cease spreading.
Remember, they will eat just about anything except roads, bridges, and public buildings.
